How to play
“Touch” means sharing an edge. Diagonals never count.
Drag a piece onto the 5×5 frame. Tap it, or press R, to rotate. Press F or the flip button to mirror it. Arrow keys move the piece you are holding, and Enter places it.
Every piece has a color, a pattern, and a shape name, so the rules are not color alone. When every rule holds, lock it in. One shot a day. Rarer layouts score higher.
